To allie/wm t may concern.'

Be it known that I, EnAsrUs E. lfVINnLnY, a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in a Machine for Use in the Manufacture of Shoes; and I do hereby declare the following to be a full, clear, and enactdescription of the invention, such as will enabl-e others skillet in the art to which it appe-rtains, to make and use the same. y

This invention relates to machines for use in the iinanufacture of shoes and more. particularly to machines for use inthe manufacture of shoes having short outsoles.

ln shoe bottoms composed of a heel and a short outsole, the base of the heel is recessed or cut away adjacent to the breast end thereofjto receive the rear or heel-seat end of the outsole, the rear extremity of the sole and the recess in the heel being severally so shaped that the former will exactly .lit into thel la ter. Inasmuch as the sole is laid on the shoe before the heel is attached, it .is essential that the rear end of the solo shall be accurately located in a predetermined position with respect to the rear of the shoe in order that the heel, when subsequently adjusted in assembled relation with the sole, 'shall be properly positioned relatively to the upper.

The principal object of the present invention is to provide means for insuring the proper location of the rear or heel s at end of a short outsole with respect to the rear of the shoe.

With this object in vview a feature of the invention consists in the provision of a locating or gaging device for engaging the edge of a short loutsole at the heel seat end thereof to locate the sole in its own plane relatively to a shoe prior to 'the securing of the sole to the shoe. In its preferred form this feature ofthe invention consists in the provision of means especially designed for determining the exact location, both longitudinally and transversely with respect to a shoe, of the heel-seat end of a short outsole such as that illustrated and described in Patent No. 1,396,801, issued Nov. l5, 1921 on my application. In the illustrated machine the positioning of the heel-seat end of the sole is effected by means of gage members which are adapt-ed to be manually moved into operative position before the sole is placed on 'the slice and are auto .matically retracted from the shoe before the application of pressure to the sole. lt is to be understood, however, that the invention is not limited to the specific construction and arrangement shown except in so far as delined in the claims.

Other objects of the invention are to provide improved means for accurately locating the` forepart of a sole upon a shoe, to provide improved means for 'securing the sole to 'the shoe, and to provide a slice-supporting jack of improved construction which may be moved into a different angular position relatively to the machine after the shoe has been operated upon, in order to facilitate the removal of the shoe from the jack and the placing of another shoe thereon. The features of the invention by means of which these objects are obtained are not limited to use in connection with 'the manufacture of shoes having short outsoles but are also adapted for use in operating upon slices having ordinary or full length outsoles.

The invention further consists in certain constructions, combinations and arrangements of parts hereinafter described and claimed, the advantages of which will be obvious to those skilled in the art.

A. sole laying machine embodying the various features of the present invention in their preferred form is illustrated in the accompanying drawings,` in whichz- Figure l is a view in side elevation of the machine; Fig. 2 is a view in front elevation of the machine with portions 'thereof broken away; Fig. 3 is aiview of a portion of Fig. l on an enlarged scale showing a different position of the carrier upon which the shoe supporting 'ack and the sole locating devices are mounted; Fig. 4 is a view in side elevation and on a still larger scale 'showing the jack with a shoe placed thereon; Fig. 5 is a view in side elevation of the mechanism shown in Fig. 4 looking` from the left; F ig. 6 is a view in side 'elevation of the gagging device for positioningl the heel seat end of the sole; Fig. 7 is a top plan view of mechanism shown in Fig. 6; Fig. 8 is a view in side elevation. of the locating or centering device for the forepart of the shoe; Fig. t) is a view in end elevation of said locating device.; F ig, l() is a detailed view of a portion of the mechanism shown in Fig. S looking from the left; and Figs. ll, 12 and 13 are resp ctively side, plan, and end views showino' a modified form1 of the gaging devicel ror the heel seat end of the sole.

The present invention in its preferred form is embodiedin a double machine which is adapted to operate upon right and left shoes. To this end two groups of operating` mechanism are arranged side by side and supported upon frame com )rising a base or body portion 2O having twin standards 22 rising` therefrom. Both groups of mechanism being. similar in construct-ion and mode of operation; one group only is illustrated in its entirety in the drawings. A. stationary shaft 24 is supported in the base 2O and the machine is driven by a driving pulley 26 which is rotatably mounted at the middle of said shaft and is adapted to be connected with any suitable source of power. ln order that the mechanism on one side of the machine may be driven independently of the mechanism on the opposite side thereof a suitable treadle controlled one `fevolution clutch member 28 is rotatably mounted on the shaft 24; at either side of the pulley 26, as shown in Fig. 2, and each clutch ni mher 28 is adapted to connect the associated operating mechanism with the driving` pulley 24 when actuated by its treadle, as occasion may require.

The mechanism illustrated comprises; in general, a shoe supporting` ack 36 comprising a heel support 32 and a toe support 34; a jack-carrier 86 to which the heel and toe supports are adjustably secured and which is mounted for oscillatory movement so that the jack may be swung to and from a convenient shoe receiving position; a head 38 to which the carrier 36 is pivotally secured and which is adapted for vertical reciprocatory movement so that a shoe which has been placed upon the jack and upon which an outsole has been located may be moved to and from pressure receiving position; a gaging device 40 which is supported above the carrier 36 and serves toV determine the position of the rear or heel seat end of the sole with respect to the shoe; a locating or centering` device 42 that is mounted on the toe support and is adapted to center the forcpart of the sole upon the shoe; a sole-pressing form or pad 44 that is carried by a portion of the standard 22 which overhangs the jaclr and which is forced downwardly to supply pressure to the sole; and a nail driving mechanism 46 that is also supported on the standard 22 and by means of which nails are driven to permanently secure the heel seat end of the sole to the shoe.

The heel and toe supports and 34 l and 4) are both mounted upon a bed plate 50 which constitute a portion of the jack and is dovetailed in the top of the jack-carrier 36 for longitudinal movement thereon to permit the shoe to be adjusted forwardly or rearwardly in the machine. rlhis movement of the bed plate is effected by the manipulation of a hand screw 52 which is mounted to turn without longitudinal movement in the carrier and is threaded into a lug' 54 depending from the bed plate 50.

The heel support 32 (Figs. 4 and 5) cemprises a block 56 havingl a spindle 5S which enters the last on which the shoe to be operated upon is placed; a post 60 to which the block 56 is pivoted and a base 62 havinguprights 64 rising therefrom between which the post 60 is rigidly but adjustably supported. rlhe pivoted bloot; 56 is acted upon by a spring pressed plunger 66 in the post 60 which tends to tilt the block in a direction bringing a stop block 68 projecting therefrom into engagement with a shoulder 70 on the post 60. The post 60 is secured in adjusted position by means of a clampingbolt 72 which extends through a slot 14 in the post and through the uprights 6". The slot 74 permits upward and downward adjustment of the post 60 between the uprights 64 when the clamping bolt 72 is loosened; and the post is at all times guided by means of ribs 76 formed thereon which are received in grooves in the uprights 64. The adjustment of the post 60 is effected by the turning of a nut 78 on a screw 8() which is secured to the lower end of the post 60; the nut beingprevented from moving longitudinallj.' with the screw by reason of its confinement in a recess 82 (Fig. 5) in the base 62. In order that the nut 78 may be conveniently operated; worm gear teeth which are formed upon its periphery are engaged by the teeth of a worm 84, the worm being secured to a shaft 86 that is urnaled in the base 62 and provided with a knurled head 88 by which it may be manipulated. The base 62 is dontailed onto the bed plate 5() of the carrier 36 for adjustment toward and from the toe post 34 and is secured in adjusted position on the bed plate by means of a screw 9() ei;- tendinnj through a slot 92 in the base 62 and through one or another of a plurality of tapped holes 94 in the bed plate.

The toe support 34 (Fig. 4) comprises a toe rest 96; a post 98 to the top of which the toerest is secured, and a standard 100 in which the post 96 is adjustably supported.

ylhe standard 100 is dovetailed 4at its base upon plate 102 order that the toe sup'- port 34 may be adjusted transversely oit' the carrier 36, while the plate 102 is in turn dovetailed onto the bed piate of the carrier to permit adjustment of the toe yrest longitudinally with respect to the carrier. The adjustment of the toe rest upon the plate 102 is permitted` by loosening` one or more set screws 104 which normally serve to hold the standard in adjusted position. rihe adjustment of the plate 102 longitudinally of the bed plate 50 is effected by an adjustscrew 106 that is mounted to turn without longitudinal movement on the bed plate and is threaded into a lug 106 depending` from the plate 102. rllhe post 96 is screwthreaded throughout a portion of its length and is provided with a hand actuated nut 110 by means of which the post and the toe rest 96 may be raised or lowered to adjust the longitudinal angular position of the shoe. The nut 110 is prevented from moving longitudinally on the post 06 by reason of its coniinement between the top of the standard 100 and the under side of a retain-ing finger 112 which is secured to the standard and engages the top of the nut 110. The post 96 is prevented from turning with the nutby means ofa projection 111 V(Figs.

4 and 0) on the tinger 112 which enters a longitudinal groove 113 in the post.

During the operation of the machine the jack-carrier 36 is supported with the bedplate 50 in a substantially horizontal position and with the shoe located directly beneath the sole pressing form 44. ln order that the jack-carrier may be swung out from beneath the pressure-form to permit removal from the jack of a shoe which has been operated upon and the placing of another shoe on the jack, the jack-carrier 36 is pivotally mounted on studs 114 which project from the head 36' and ex end'through the opposite sides of the carrier. The pivot i studs 114 are so located with respect to the center of gravity of the jack-carrier that the latter may be swung by gravity into the position shown in Fig. 3 wherein the jack is conveniently located for the removal or reception of a shoe. which a sole has been laid has been removed from the j ack another shoe is placed thereon which is ready to receive an outsole. The solo is then located on the shoewith the aid of the locating devices 40 and 42 which willv presently be described. After the sole has been located on the shoe the jack-carrier 86 is tilted upwardly to bring the shoe beneath the pressure-form 44, and said carrier is hitched` in this position upon the head 36. The head 66 is then raised, bringing the carrier and the shoe into the position shown After the shoe upon in Fig. 1, wherein the sole of the shoe is ready to receive pressure from the form or pad 44.

The gagmg device 40 (Figs. 6 and 7) for locating the heel seat end of the sole comprises a pair of forwardly extending1 gagemembers or positioning arms 116 which are severally pivoted for horizontally swinging movement about studs 116 that are secured in an upright 120 rising from the jackcarrier 36. The positioning arms 116 are severally provided on their under sides, near the free ends thereof, with gage-blocks or abutments 122 having curved positioning faces 124 that are adapted to engage correspondingly shaped edge faces at the rear of the sole 126. A full description of the sole herein illustrated will be found in the United States Letters Patent No. 1,396,801, issued Nov. 15, 1921 on my application. The extremities of the arms 1,16 are adapted to overlap the outer face of the sole to assist in retaining the sole in adjusted position and are slightly bevelled at 128 to facilitate the positioning of the sole against the gage blocks 122. The arms 116 are connected to .move in unison by means of `a slide 130 that` is supported and guided in the top of the upright `120 and is provided with rack teeth 182 at its opposite longitudinal edges which intermesh with segmental gear teeth 134 that are formed on each of the arms 116.` Rearward extensions 136 of the arms 116 are connected by a spring 138 tending to force the free ends of the arms outwardly and away from the shoe.` Handles 140 are formed on the arms 116 by means of which the arms may be swung' inwardly into operative or sole engaging position, and means is provided for retaining the arms against the tension of the spring 138 in the position into which they are moved. The retaining means consists of pawl 142 which is pivoted at the top of the upright 120 and is forced downwardly by a spring 144 into engagement with ratchet teeth 146 on the upper side of the slide 130. r1`he pawl 142 is upwardly extended to provide a releasing finger 148 which when depressed will swing the pawl out of engagement with the ratchet 'teeth in the slide 130 and restore the arms 116 to inoperative positions. The engagement of the pawl 142 with a stop lug 147 at the rear end of the slide 130 limits the voutward movement of the arms 116 and deslide 180 so as to be moved in an opposite direction thereby. The connection between the slide and the gage member 150 comprises a pinion 152 that is rotatably mounted in the upright 12() andy so arranged that its teeth mesh with rack teeth 154 on the under face of the slide and with rack teeth 156 on the upper face oi plate 158 which is secured to the gage member by means of a bolt 160 extending through a longitudinal slot in the plate 158. The head oiE the bolt 160 projects upwardly through a slot in the slide 180 so that it may be conveniently Aengaged by a wrench and loosened to permit relative adjustment of the plate 158 and the gage member 150. In this way the operative position oi the arms 116 with relation to the medial line of the shoe may be varied in accordance with shoes of diderent sizes and stylesv without varying the operative positions ot the arms 116 relatively to the rear end ol the shoe. The latter relation, which determines the longitudinal location ofthe rear extremity of the sole, is obtained by releasing the gage member 150 relatively to the plate, shifting the jack 36 toward the upright 120 to bring the shoe into proper relation to the arms 116, and then adjusting the gage 'member V150 in the plate 158 to correspond.

In order to adjust the gaging device 40 for a shoe of a given style or size, the shoe is iirst placed upon the jack and the sole is manually located in proper position on the shoe. rIChe jack is then adjusted on the car rier 36 and the arms 116 are swung inwardly toward the shoe until the positioning faces 124- o'f the blocks 122 are brought into en gagement with the corresponding edge faces of the sole. I.Vith the arms 116 held in their adjusted positions by the engagement of the pawl lil-2 with the ratchet teeth 146, the gage member 1.5() is brought forward intocontact with the rear of the shoe, the screw 160 having been previously loosened to permit relative movement between the gage 150 and the plate 158. After the pawl 142 has been released to permit the arms 116 and the gage member 15G to return to their normal or inoperative positions, the gaging device is in readiness for operation.

The gaging device fi() having been properly adjusted, a shoe upon which an outsole is to be laid is placed on the jack and after the j ack has been swung upwardly to bring the shoe into position to be operated upon, the positioning arms 116 are swung toward each other, by means ci the handles 140 until the gage member 15() comes into contact with the'rear of the shoe. rihe arms 116 are then in operative position, as shown in Fig. 7, and the operator places the sole on the shoe, inserting the shank end thereof beneath the beve-lied extremities of the arms 116 and forcing the curved edge portions ot the shank end of the sole against the curved positioning faces 124 whereby the rear oll the sole is located both longitudinally and laterally with respect to the shoe.

fitter the sole has been placed upon the shoe and its heel-seat end has been located by the gaging device 10, the locating device 112 is operated to position the torepart of the sole upon the shoe. The locating device l2 (Figs. 8, 9 and 10) comprises a pair et upright arms 162 which are vertically movable toward and from the sides of the shoe. To this end the arms 162 are secured at their lower ends upon rock shafts 164, Each rock shait 1611 is journaled in bearing lugs 166 projecting from a gage carrier 168 which is mounted upon the toe support 84 and is movable thereon to move the arms 162 downwardly away from the shoe so that the shoe may be swung laterally otiq from the tee rest 96 before it. is removed 4rom he spindle The arms 162 each comprise upper and lower members which are secure-d together y a bolt 170 and wing nut 17 2, the belt ef;- tending through a longitudinal slot in the upper member oi the arm and thereby permitting relative adjustment ot the arm members to lengthen or slierten the arm. fadjustably but rigidly secured' by means oi a bolt 1711 to the top of each arm 162 is a gage bloclr 176 which carries relatively adjustable gages 178 and 17.9 for engaging the lateral edge of the liorepart oi" the sole and of the upper respectively. Each gage 178 is guided in the block 176 for movement toward and from the sid-e of the shoe and is secured in position by means of a screw 180 extending through a slot in the gage. It is often desirable to have ,the Jorepart of the sole project slightly more at one side ot the shoe than at the op posite side and the desired unequal projection of the sole may be secured by the adjustment of the gages 178 on the gage blocks 176. By loosening the nut on the bolt 174i-, the gage block may be adjusted angularly to bring the gage into alignment with the plane of the sole.

In order that the arms 162 may be operated to eii'eot the positioning oi the ilorepart o'l the Sole on the shoe, the arms are connected to move in unison toward and from the opposite sides oi" the shoe by means of interineshing segmental gears 182 which arel secured to the rock shafts 164. In positioning the sol-e, the arms 162 are swung` manually toward the shoe. and are locked in sole engaging position by means of one or the other of the two upright spring ingers 184 which are pivoted at their lower ends on a cross bar 186 connecting the opposite sides of the carrier 168, the upper ends of each linger being provided with ratchet teeth which are adapted to engage similar teeth termed on a ratchet segment 186 that is secured to the side of the'corresponding segmental gear 182. These fingers 184 are. connected by a spring `188 tending to swing them toward each other and out of operative engagement with their respective ratchet segments. Vhen the centering gages 42 are in working relation with the sole, as indicate-d in Fig. 1, the spring-fingers 184 are held against the ratchet segments 186 by means of a wedge 190 which projects from the standard 100 between the lingers 184 holding them apart against the tension of the spring 188. The ratchet teeth on the lingers v184 are so arranged relatively to their respective `ratchet segments 186 that when the teeth of one of the fingers are in holding engagement with the teeth of the cooperating ratchet segment, the ratchet teeth of the opposite linger are disposed with their holding faces located midway between the top and bottom of the inclined faces of the cooperating ratchet segment.` InV this Way a very fine adjustment of the centering gages may be secured.v j

The operation of locating the sole with the aid of the devices Vdescribed `may beA performed with facility and despatch by a relatively unskilled workman.V `The use of the gaging device for the heel seat end of the sole insures the locating thereof in exactly the required position so that when the heel is fitted to the heel-seat it will be properly located with respect to the shoe; By means of the centering device the forepart of the sole is accurately centered upon the shoe `without the necessity of the exercise of eX- treme care and precaution upon the part of the operator that is required when soles are :fitted in the ordinary manner. Moreover the soles may be cut very closely to the size ultimately desired inasmuch as it is not necessary to make allowance for improperly lceating the soles and consequently there is very little material wasted when subsequently trimming the edges of the soles.

The positioning gages for the forepart of the shoe are arranged to be released from sole engaging position by a pressure of the form 44, after they have performed their j locating function, in order that they may be swung out of working relation with the sole into a position where they will not interfere with the removal of the shoe from the jack and the placing of another shoe thereon. To this end, the gage .arms 162 are mounted upon the gage carrier 168 so as to be movable in a vertical plane at right angles to the planeof oscillation of the gage arms 162 and means is provided for latching the carrier in operative position and for automatically tripping the latching means upon the appli cation of pressure to the sole by the form 44. The carrier 168 is held in operative position by means of a latch 192 that is secured to a stud 194 which is free to turn in bearings at the rear of the standard 100, and a spring 195, surrounding the stud 194, tends to hold the latch in position to engage a shoulder 196 on the top of the carrier 168. The pivotal connections between the gage carrier 168 and the standard 100 are arranged at the rear of the center' of gravity of the carrier so that the carrier will drop by gravity into inoperative position when the latch is tripped. This connection comprises a stud 198 which supports on `its extremities the carrier 168, the stud extending through slots 200 in the sides of the standard 100 and through a plunger 202 that is located in a recess in the standard 100 and is pressed upwardly by a stiff spring 204 so that the stud is normally forced against the upper ends of the slots 200. With an arrangement of this sort,\the gage carrier 168 and the arms 162 are permitted to yield downwardly a small amount when engaged by the pressure form 44, and in order that this slight downward movement may be utilized to trip the latch 192, the plunger 202 is operatively connected with the latch in the following manner. A hook 206 which projects Vfrom the rear of the plunger 202 through a slot in the stand ard 100,engages a pin 208 projecting laterally from a link 210 which is pivotally secured to an arm 212 that is fixed to the stud 194. By means of this construction, not only is the shoulder 196 depressed rela tively to the latch 192 when the gage-carrier 168 is forced downwardly, but the latch 192 is lifted an amount equal to the downward movement of the shoulder, so that the unlatching of the carrier is effectively accomplished. The downward tilting movement of the carrier is limited by the engagement of pins 214 projecting from opposite sides of the standard 100 with the upper end of the arcuate slots 216 in the opposite sides of the carrier, into which the pins extend. As the gage-carrier tilts forwardly after being released from operativeposition, the spring fingers 184 are moved away from the wedge 190 which is mounted on the stationary standard 100 and the spring 188 swings them out of engagement with the ratchet segments 186 thus permitting the arms 162 to swing backwardly from the sides of the shoe by gravity until their movement is arrested by the engagement of downward extensions 218 of the arms with the sides of the gage-can rier 168. After another shoe has been placed on the jack, the gaging device is lifted into working relation with the shoe and its movement in this direction islimited bythe engagement of the pins 214 with the bottom ends of the slots 216.

lifter a short outsole has been properly positioned on the shoe with the aid ofthe locating` devices and 42, the j acl; carrier 36 is swung upwardly about its pivots 114 to bring the sole directly beneath the preslli) sure form 44, this position being determined by the engagement of an adjustable stop screw 220 wit-h the front of the frame standard 22. The ack carrier is held in this position by means of a latch 222 (Figs. 1 and 3) which is maintained by means of a spring 224 in engagement with a shoulder 226 formed on a plate 227 that is secured to the head 38. In order that the shoe may be raised intoposition to be operated upon, the head 38 upon which the jack carrier is mounted is secured to the top of a shaft 228 which is guided to reciprocate vertically in a bearing 230 in the base 20. rlhe head 38 reciprocates in sliding engagement with the main standard22, a vertical guiding rib 232 on the standard 22 being received in a groove in the head and serving to prevent the head from turning. The head is actuated to raise the shoe into position for the application -of pressure to the sole and the driving of the nails into the heel seat end thereof, and to lower the shoe after the sole .has been laid, by means of a toggle ccmprisinga pair of links 234 constituting one arm of the toggle and a link 286 constituting` kthe other' arm of the toggle, the arms being pivoted together at 288. rthe upper ends of the links y234 are pivoted at 240 on the opposite sides of a sleeve that is loosely mounted on the shaft 228 while the lower end of the link 236 is pivoted at 244 to a bracket on the base 20. The knuckle joint 238 of the toggle is connected by a pair of links 246 to, a lever 248 which is pivo-tally mounted on a stud 250 in the base 2O and is provided with a cam roll 252 which enters a groove in a cam 2:54 on the main shaft 24. As the toggle is straightened, the head 38 is yieldingly raised through coiled spring 256 which -eneircles the shaft 228 between the sleeve 242 and a collar 258 that is positioned beneath a shoulder on the shaft. As the toggle is being broken, the downward movement of the sleeve 242 is transmitted to the shaft 228 through a collar 260 fixed to the lower end of -the shaft.

When `the main shaft 24 is connected through it-s clutch 28 with the drive pulley 26, the cam 254 operates to raise the shoe into. position to be operated upon. In order that `the shoe may be rigidly supported for the sole pressing and nail driving operations, a pair of supports 262 are oscillated into position beneath the lower edge faces 268 of the sides of -the yjack carrier 36, These supports 262 are secured to a rock shaft 264 and are each vprovided with acircular wedge face 265, eccentric -to the axis of the shaft 264, which swings into wedging contact with the faces 263 .O the jack carrier. The rock shaft 264 is journaled in a port-ion of. the bearing 230 and ysecured to thel rock shaft is a pinion 266, the teeth of which intermesh with segmental teeth for-ined on a cam leve the lever being fulcrumed at 270 on the base 20 and carrying a cam roll 272 which is held by a spring 274 against the periphery of a cam 275 which is fast on the hub 276 of the rotatably mounted clutch member 28.

When the shoe is in position to be operated upon, the heel seat end of the short outsole is engaged and firmly held in place against the shoe by means of the lower extremities of two nail throats 277 of the nail driving mechanism 46, the shoe being forced upwardly against the throats by the spring 256. Just as the sole comes into engagen'ient with the nail throats, the gage arms 116 are released from operative position and are moved outwardly by the spring 138 so that they will not interfere with the application of pressure to the sole by the pressing form 44. rlChe release of the arms 116 is effected at the end of the upward movement of the jack carrier by the engagement with the releasing finger 148 on the -pawl 142 of an adjustable abutment 278 (Fig. 1) depending` from the forwardly extending portion of the frame standard 22. The sole is now held in position on the shoe by the engagement therewith of the nail throats 277 and the locating devices 42 and is ready to be acted upon by the pressing forni 44.

The pressing form 44 comprises a continuons elastic pad that is suspended from a plurality of separate hangers 280 which support the pad atintervals throughout its length and are connected by pressure distributino' or equalizing mechanism 282 with a movable carrier 284. The pressure pad with its supports and pressure distributing mechanism is similar in construction and mode of operation to that of corresponding pai-ts illustrated and described in Patent "lo 694,867, granted March 4, 1902 to H. Gifford, and is adapted to automatically adjust itself to operate effectively upon slices of different sizes.

The carrier 284 for the pressing forni or pad 44 is movable vertically and to this end is provided with ujfiwardly extending arms 286 which are guided in ways formed in a bracket 288 projecting forwardly from the standard 22. rlhe carrier 284 is suspended from and actuated by a pai-r of toggles each consisting of a link which is pivotalljv connected at 292 with the bracket 288 and which constitutes one arm of the toggle, and a pair of links 294 which are pivotally connected at 296 wit-h the carrier 284 and which constitute the other arm of the toggle, the twol arms being connected by pivot studs 298 and the pivot studs 298 being connected by a link 300. The rearmost of. the pivot studs 298 is connected by a link 302 with the upper end of a cam lever 304. The cam lever 304 is fulcrumed at 306 on the frame standard 22 and carries a cam roll lflfl 303 which enters agroove in a cam 3107 the cam being secured to a shaft 312 that is journaled in suitable bearings on the standard 22. The cam 310 is driven through intermeshing spur gears 3147 one fixed to the shaft 312 and the other to a eountershaft 316 that is also j ournaled in bearings on the standard 22. The. countershaft 316 is driven from a vertical shaft 318 through intermeshing bevel gears 320. The vertical shaft 318, which is journals-d in bearings on the standard .22, is in turn driven from the main shaft 24 through intermeshing bevel gears 322.

In the construction shown, the nail driving mechanism 46 is provided for driving' nails or tacks to secure the heel seat end of the sole to the shoe. This mechanism is similar to that disclosed in Patent No. 15106393, granted August l), 1914 to F. L. MacKenzie, except that the present mechanism is adapted to drive two nails simultaneously. To this end a single hopper 324 and duplicate sets of devices are provided, one set arranged on each side of the standard 22 and including a driver 326 which operates in one of the nail throats 277, a separator 328 which delivers tacks to the driver and a race way 330 which supplies tacks to the separator. The tack driving mechanism is driven by means of a sprocketchain 332 which passes over a sprocket-wheel 333 on the shaft 316 and a similar sprocketwheel 334 on the main shaft of the tackdriving mechanism. This mechanism is adapted to drive two tacks through the heel seat end of the outsole substantially in the positions indicated at in Fig. 't'. The tacks 335 project through the insole against the inner face Vof which they are clenched by contact with the last in the shoe.

Before the cycle of operations of the machine is completed the pressure pad 44 is raised and the head 33 is lowerech each to their initial inoperative positions, the supports 262 having been first oscillated out of supporting engagement with the jack carrier 36. As the head 33 moves downwardly, the latch 222 is disengaged from the shoulder 226 by a trip device comprising a pawl 336 that is pivoted at333 on the framestandard 22 and is normally held in the path of the latch 222 by a spring` 340. The pawl 336 is so arranged that-.when the head 33 is in its lowermost position and the jack-carrier is swung upwardly thereon, the pawl will yield rearwardly under the horizontal pressure of the latch 222 to permit the latch 222 to engage the shoulder 226 on the plate 227. When the head 33 rises, the pawl 336 slips under the end of the latch, and when the head descends again the latch is forced upward from the shoulder 226 vand the jackcarrier falls by gravity until said latch engages a shoulder 342 on the plate 227 as indicated in Fig. 3. The shock of the downward movement of the carrier 36 is absorbed by a 'cushioning device consisting of a spring pressed plunger 344 which is guided in the head 33 and engages a surface 346 on the under side of the jack-carrier.

In Figs. ll, l2 and 13 is Shown a modified form of locating device for the heel seat end of a short outsole in which graduations are provided for the purpose of hdetermining the positions of the gage `members for shoes of varying sizes and sty/iles. In this construction a pair of spaced apart gage` members are provided for engaging the rear ofthe sole. These gage members 356 are carried by an arm 352, each member being secured to the arm by a bolt 354 and provided with a ridge 356 which enters a corresponding groove in the arm to prevent the gage member from turning on the bolt The bolts 354 extend through slots353 so arranged in the arm 352 that Iwhen the bolts are loosened, the gage members may be adjusted toward or from each other to adapt them for engagement with soles of different widths. The position of the gage members for shoes of different sizes may be determined by the relation of a mark or pointer360 on each ofthe gage members and a scale 362 on the arm adjacent the pointer. The arm 352 is mounted on the upright 120 for vertical swinging movement so that the members 350 may be swung out of working relation with the soleV before the shoe is removed from the jack." To this end the rear extremity of the arm 352 is bifurcated and secured'to stud 364 projecting from the upright l26 between the bifurcated ends of the arm 352. The arm with the members 350 is adapted to be swung into a substantially horizontal position for engagement with the sole and is held downwardly against the shoe by a coiled spring 363 one end of which is secured. to a pin 370 en the upright 120 while its opposite end .is secured to a pin 37 2 on an arm 3274 secured to the stud 364. Tov permit removal of the shoe from the jack aiter the sole has been laid thereon, the arm 352 is swung upwardly and rearwardly in inoperative position, this position being determined by the engagement of a stop lug 376011 the arm 352 with a shoulder 373 on the upright 120. The position of the arm 374 on the stud 366 is such that the pin 376 on which the spring 363 is secured is located forward of the center of the stud 364, when the arm 352 is in operative position, and that said pin is located to the rear of the center of the stud 364 when. the arm 352 is in inoperative position7 so that the arm is held in i both positions by the spring 363. The location of the rear end of the short outsole with respect to the rear of the shoe is determined by means of a cylindrical gage member 380 which is supported and guided on the upright for horizontal sliding movement. ln order that the gage member 380 may be correniently adjusted toward and from the shoe to vary the longitudinal location of the gage member-s 350, adjusting means are provided comprising a worm wheel 382 that is rotatably mounted on a pin 38aA in the upright 120, the teeth of the worm wheel meshing with rack teeth 386 at the bottom of the sliding gage member 380. The worm wheel 382 is rotated by a worm 388 on a shaft 390 that is mounted to turn in bearings in the upright 120. The shaft 390 is adapted to be rotated by means of a knurled head 392. The position of the gaging member 380 may be determined by the relation of the divisions of a scale 394;'with the adjacent bevelled edges 396 of the bearing in the upright 120 in which the gage is adapted to slide, After the required adjustment of the sliding gage member 380, the jack is moved to bring` the rear of the shoe against the gage member.
